Definitions

  • Apparatuses for igniting combustible materials comprising a body, a tank of liquefied gas, this tank being provided with a valve controlling the passage of gas towards a burner carried by the body, the latter comprising means for ignition of the gas reaching the burner and a control member of these ignition means, the burner being of the type comprising an air-gas mixer with air intake passages to create a fuel-oxidant mixture, followed by a combustion chamber having an inlet for said mixture and an outlet for the ignited mixture.
  • a body a tank of liquefied gas
  • this tank being provided with a valve controlling the passage of gas towards a burner carried by the body, the latter comprising means for ignition of the gas reaching the burner and a control member of these ignition means
  • the burner being of the type comprising an air-gas mixer with air intake passages to create a fuel-oxidant mixture, followed by a combustion chamber having an inlet for said mixture and an outlet for the ignited mixture.
  • the object of the present invention is to further improve the wind resistance of the flame.
  • the ignition device according to the invention is characterized in that the length of the chamber, taken in the direction of passage of the air-gas mixture, is at least equal to 1.5 times the smallest width of this chamber taken transversely to said direction of passage of the mixture.
  • the apparatus according to Figures 1 and 2 comprises a body or housing consisting of two parts 1 and 2a, 2b assembled along an oblique line 3 provided with a seal 4 made of plastic.
  • This box contains a tank 5 of liquefied gas, this tank being provided with a valve 6 controlling the passage of the gas towards a burner comprising a combustion chamber 7 of ceramic material and arranged obliquely with respect to the longitudinal axis of the box.
  • This combustion chamber is retained in part 1 of the housing by elastic elements constituted by leaf springs, of which only one 8 is visible in the drawing. In this way, the room which is fragile, is sheltered from shocks.
  • the chamber 7 has an inlet 9 in which the gas coming from the valve 6 is supplied by a tube 10 , the end of which has an injector 11 .
  • the gas leaving this injector entrains combustion air towards the chamber 7 and the gas-air mixture can be ignited by a spark gushing between the electrodes 12 and 13 , this spark is introduced by a piezo generator 14 electric.
  • the chamber 7 contains on the side of the intake passage 9 a wick 15 of ceramic fiber arranged transversely in this chamber near the base of the flame and on the path of the air-gas mixture. At least some of these fibers are frayed. As a result, if the wind pushes the flame towards the bottom of the combustion chamber, which could extinguish it, these fibers are first immersed in the ignited gas and brought to very high temperatures, so that the incandescent fibers immediately rekindle the flame. Furthermore, this wick 15 constitutes an obstacle which lowers the speed of flow of the gas in the chamber 7 .
  • the length of the chamber 7 , taken in the direction of passage of the air-gas mixture is at least equal to the smallest width of this chamber taken transversely relative to said direction of passage of the mixture.
  • This arrangement contributes to the good maintenance of the flame, even in strong winds.
  • the apparatus further comprises an ignition control member, this member being constituted by a handle 16 pivoted relative to the housing by a link 17 and two plates 18 rotating around a pivot 19 and playing the role of links. Only one of these plates is visible in the drawing.
  • the handle 16 is articulated on the plates 18 by a pivot 20 , and on the link 17 by a pivot 21 .
  • a spring 22 acting on the pivot 21 and hooked at 23 on the body of the lighter returns the handle 16 to its rest position illustrated in FIG. 1 .
  • the plates 18 control several organs for the use of the ignition device.
  • the two plates are connected together by a transverse rod 24 which passes over a lever 25 for controlling the opening of the valve 6 .
  • the plates also have a part 26 forming a cam and engaged in a notch 27 of a fork lever, articulated at 28 , which carries a cap 29 placed opposite an opening 30 of the shell 2a opposite the combustion chamber. 7 .
  • the plates 18 are also articulated at 31 on a U-shaped part 32 and the base 33 of which cooperates with the actuating part 34 of the generator 14.
  • the plates 18 are pivoted in an anti-clockwise direction. This pivoting causes an opening of the valve 6 by action on the lever 25 , the tilting of the cap 29 to release the opening 30 and the actuation of the piezoelectric generator 14 to cause the ignition spark between the electrodes 12 and 13 .
  • the generator 14 is provided at its upper end with a contact 35 against which comes to bear a spring 36 housed in a bore in the body 1 and which is connected to the electrode 13 to ensure passage ignition current. Thanks to this arrangement, the problems usually encountered when the generator is connected by an external wire welded to the ignition electrode are avoided, since this wire is fragile and is easily broken.
  • FIG 3 shows the upper part of an igniter which differs from that shown in Figure 2 only by the combustion chamber and the supply of gas thereto.
  • the reservoir 5 is provided with a valve 6 which directly carries the ejector 11 .
  • This ejector is directed in the axis of a hole 40 in the shape of a Venturi which is formed in a part 41 .
  • the latter further comprises a cylindrical chamber 42 , the axis of which is inclined relative to that of the Venturi to allow the combustion air to easily supply the hole 40 in the form of a Venturi, slots 56 are provided in the wall of the housing. the igniter.
  • the ejector 11 and the Venturi constitute the air-gas mixer, which makes an angle relative to the direction of the inlet orifice and outlet of the combustion chamber 7 .
  • the latter is made of ceramic and is engaged in a bearing of the part 41 .
  • the air-gas mixture To pass from the chamber 42 to the combustion chamber, the air-gas mixture must pass through a body 43 which is intended to slow the flow speed of the mixture.
  • This body 43 is shown in more detail in FIGS. 4, 5 and 6.
  • FIG. 5 is a plan view of the body 43 of FIG. 4, while FIG. 6 is a view along the line VI-VI of FIG. 4.
  • This body 43 is constituted by a bush 44 having an upper wall 45 , which has been cut to form four fins 46 . These fins are oblique and cause a swirling movement of the mixture arriving from the combustion chamber 7 .
  • a part 50 in the general shape of an inverted bowl In the lower part of the sleeve 44 is engaged a part 50 in the general shape of an inverted bowl.
  • This part 50 has a central orifice 51 , as well as four openings 52, 53, 54, 55 provided on the edges of this part. These openings are not aligned with the openings in the wall 45 obtained during the formation of the fins 46 to 49 , so as to produce an additional baffle helping to slow down the speed of the air-gas mixture.
  • the passage of the mixture is thus obtained in chamber 7 at a speed much lower than the speed of propagation of the flame in this mixture, so that the combustion reaction is maintained in the chamber and that the risk of seeing is entirely eliminated. the flame will escape from the chamber to the outside where it could be extinguished by the wind.
  • one or more ceramic elements such as element 15 in FIG. 1, could also be placed in the combustion chamber 7 .
  • the part 50 shown in FIG. 6 could be replaced by a fine lattice which would fulfill the same purpose, namely to slow down the speed of the gas mixture.
  • This trellis could consist of ceramic fibers which would play the same role as the wick 15 of FIG. 1 and, in this case, it goes without saying that the body 43 should be given up.
  • This piece 50 could also be replaced by a pad of ceramic fiber wadding.
